CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2012-0029651, filed Mar. 23, 2012, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a backpack type bag, and more particularly, to a backpack type bag with a self-balancing electric vehicle mounted thereon that is capable of being moved through the self-balancing electric vehicle ridden by a user, in good places or conditions for riding, and that is capable of being carried on the user's shoulders, in a state where his personal items are put thereinto, in bad places or conditions for riding.

2. Background of the Related Art

Generally, the backpack type bag of the invention is configured from an upright riding electric scooter. The upright riding electric scooter is a self-balancing electric scooter that performs riding by in real time maintaining the balancing between two wheels. While a variety of electrical processors inclusive of a Gyro sensor are being controlled by a controller, the balancing of the two wheels is in real time maintained in accordance with the inclinations of a rider's body, and forward and backward riding and the change in left and right directions are all carried out.

For example, in a state where the user stands on the upright riding electric scooter, if he inclines his body forward by a given angle, his inclination is sensed in real time through the variety of sensors inclusive of the Gyro sensor, and based upon the sensed result, the wheels are activated in the direction of the inclination by a degree where the inclination is removed, so that the overturning of the self-balancing electric vehicle caused by his inclination can be prevented, thereby allowing the position of the electric scooter to be compensated to keep safe riding. Accordingly, the upright riding can be maintained with the two wheels, while the balancing state of the two wheels is being not broken.

BRIEF SUMMARY

DETAILED DESCRIPTION

Hereinafter, an explanation on a backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention will be in detail given with reference to the attached drawings.

According to the features of the present invention, first, a user can ride a self-balancing electric vehicle on which a backpack type bag is mounted, and if riding is not needed, the user can carry the backpack type bag on his shoulders, thereby optimizing the conveniences in the carrying and moving works.

The self-balancing electric vehicle means a general upright riding electric vehicle, that is, a self-balancing electric vehicle that in real time maintains the balancing between two wheels during riding. The self-balancing electric vehicle has a variety of electrical processors inclusive of a Gyro sensor mounted thereon to maintain the balancing between the two wheels, and the variety of electrical processors are operated by the control of a controller, thereby maintaining the balancing.

The self-balancing electric vehicle is moved in accordance with the inclinations of a rider's body. In more detail, the inclinations of the rider's body are sensed in real time through the operation of the controller inclusive of the Gyro sensor, and based upon the sensed results, the wheels are activated, while the overturning of the self-balancing electric vehicle is being prevented. That is, the wheels are activated in real time in accordance with the values of the inclinations of the rider's body, so that the riding can be performed in the state where the self-balancing electric vehicle is upright.

FIG. 6 is a perspective view showing the assembled state of the backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention, and as shown in FIG. 6, a user can walk in a state of carrying a backpack type bag 10 on his back, and if riding is needed, the backpack type bag 10 is placed on the ground to lift a handle 21 therefrom, so that he can ride with the inclinations of his body by using the above-mentioned self-balancing principle.

FIG. 1 is a separate perspective view showing a frame of a backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention, and FIG. 2 is a perspective view showing a support rod of the backpack type bag according to the present invention. As shown in FIGS. 1 and 2, the backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention includes a support rod 20 serving as a frame of the invention during riding and the handle 21 mounted on the top portion of the support rod 20 in such a manner as to be drawn and taken by the rider.

As shown in FIG. 2, the support rod 20 has a housing 30 mounted on one side thereof, and the housing 30 has batteries mounted in the interior thereof to supply power to motors 51 mounted on the wheels 50 and a controller 31 mounted on the underside thereof, in which a variety of sensors inclusive of a Gyro sensor are located. Further, as shown in FIGS. 5 and 6, the housing 30 is located inside the backpack type bag 10 and serves as a bottom plate supporting items when the items are put into the backpack type bag 10.

FIGS. 3 a and 3 b are perspective views showing wheels of the backpack type bag according to the present invention, and FIG. 4 is a perspective view showing the assembled state of the parts of the frame in the backpack type bag according to the present invention. As shown in FIG. 3 a, each wheel 50 has the motor 51 mounted thereon to activate the corresponding wheel, and each motor 51 has a foot board 40 firmly mounted on the top surface thereof, on which the rider's foot is placed. After that, the support rod 20 as shown in FIG. 2 is fixed rigidly to the top surfaces of the two foot boards 40 by means of welding or fixing means like bolts, thereby finishing the frame of the backpack type bag according to the present invention, as shown in FIG. 4.

Accordingly, the user is placed on the foot boards 40, and next, if his body is inclined forward by a given angle, the variety of sensors inclusive of the Gyro sensor sense the inclination of the rider's body, thereby allowing the motors 51 to be operated by a degree where the inclination is removed. At this time, the wheels 50 are activated in the direction toward which the rider's body has been inclined through the operation of the motors 51, so that safe riding is achieved, while the balancing operation of the self-balancing electric vehicle is being maintained to the upright riding position.

FIG. 5 is a separate perspective view showing the backpack type bag separated from the frame, and as shown in FIG. 5, the backpack type bag 10 is mounted onto the frame on which the self-balancing electric vehicle is fixedly disposed in such a manner as to encompass the support rod 20 and the housing 30, thereby completing the manufacturing of the backpack type bag with the self-balancing electric vehicle mounted thereon as shown in FIG. 6.

As set forth in the foregoing, according to the present invention, the backpack type bag with the self-balancing electric vehicle mounted thereon serves as means for moving people or their items, thereby providing many conveniences in use to the rider. That is, in the process where the user carries the backpack type bag 10 into which items are put on his shoulders and moves to his destination, if he reaches a good place for riding, he puts the backpack type bag 10 on the ground to draw the handle 21 from the support rod 20. Next, he stands on the foot boards 40 and rides with the inclination of his body, and by the way, if there are stairs or severely inclined places bad for riding, or if he should take the subway or bus, the backpack type bag 10 is carried again on his shoulders, thereby allowing him to keep walking Accordingly, it is very convenient to move personal's items or people.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
